VCP-related myopathy: a case series and a review of literature.

ABSTRACT: The valosin-containing protein (VCP), a widely expressed protein, controls the ubiquitin-proteasome system, endolysosomal sorting, and autophagy to maintain cellular proteostasis. Frontotemporal dementia (FTD), inclusion body myopathy, and Paget's disease of the bone (PDB) are all caused by dominant missense mutations in the VCP gene, which interfere with these mechanisms and cause a multisystem proteinopathy. We describe phenotypic and genetic findings of five patients with four different mutations in VCP gene (NM_007126): c.278G > A (p.R93H), c.463C > T (p.R155C), c.410C > T (p.P137L), c.464G > A (p.R155H), c.410C > T (p.P137L). We analysed the patient' biopsies, all characterized by a muscular phenotype, and we executed immunofluorescence staining to evaluate the presence of prot
